Claims.

This invention relates to new and useful-in movements in weatherstripping and the primary object of the present invention is to providea concealed weather stripping attachment for doors, windows or the likethat is movable to a closed and sealed position simultaneously with theclosing movement of the structural element on which the same is applied.

Another important object of the present invention is to provide avertically movable sealing strip that is supported upon a group ofpivotal members, means for urging the pivotal members in one directionfor raising the sealing strip, and novel and improved means foractuating the pivotal members to lower the sealing strip as the door orwindow on which the same is applied is moved to a closed position.

A further object of the present invention is to provide a weatherstripping attachment for doors and the like including a movable sealingstrip, and adjustable resilient means acting upon an actuating member tolower the sealing strip within selected limits.

A still further aim of the present invention is to provide a weatherstrip that is simple and practical in construction, strong and reliablein use, small and compact in structure, neat and attractive inappearance, relatively inexpensive to manufacture, and otherwise welladapted for the purposes for which the same is intended.

(Ether objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Fi ure l is a fragmentary perspective view of a door structure andshowing the present invention applied thereto, and showing the door inan open position;

Figure 2 is a longitudinal vertical sectional view taken substantiallythrough the center of Figure 1, and showing the door in a closedposition;

Figure 3 is an enlarged transverse vertical sectional view takensubstantially on the plane of section line 33 of Figure 1;

Figure 4 is a fragmentary perspective view of the support member used inconjunction with the present invention; and

Figure 5 is a perspective view of one of the pivotal members used inconjunction with the present invention.

, Referring now to the drawings in detail, where" in for the purpose ofillustration, there is dis closed a preferred embodiment of the presentinvention, the numeral l0 represents a hinged or pivotal structuralelement or main support, such as a-door or the like that is movabletoward a fixed frame or casing l2.

The lower marginal edge 14 of the door I5 is provided with a verticalrecess or chamber iii in which there is mounted a housing or a pair ofend plates'iS and 29 that close the ends of the chamber it. The loweredges of the end plates 18 and 2G terminate in plane that is coplanarwith the lower marginal edge [4 of the door i The numeral 22 representsthe support mem her that is used in conjunction with the presentinvention generally. This member 22 is formed from a single strip ofbendable material such as aluminum or the like, and includes asubstantially inverted channel-shaped portion 24, the inclined legportions 26 of which are turned inwardly to provide longitudinal,channeled strips 28 that are spaced parallel to each other and to theweb portion of the portion 24.

Integrally formed with the lower longitudinal edges 38 of the channeledstrips 28 are inwardly directed, downwardly converging strips 32 thelower portions of which are turned outwardly as at 3 to providehorizontal extensions 36 that are removably secured by fasteners or thelike 38 to the marginal edge It.

The portion 24 is provided with a plurality of longitudinal spaced,notches 40 that receive pivotal members which are designated generallyby the numeral 42. The pivotal members 42 each includes a substantiallyU-shaped frame it the leg portions of which are angulated to providesubstantially L-shaped extensions 46 that are disposed in a planeperpendicular to the longitudinal axis of the frame 44.

Projecting laterally from the legs of the frames 1d, are pivot pins ortrunnions 48 that pivotally engage apertures 50 provided in the legs 26of the portions 2%,adjacent and below the notches ill, as shown best inFigure 4 of the drawings.

Fixed between the spaced parallel leg portions 52, by rivets or the like5% of a further elongated channel strip 56, is the inner portion of alongitudinal, resilient sealing strip 58, and it is noted that the legportions 52 and strip 58 are disposed between the strips 28 and thebends 34 of the strips 32, as shown best in Figure 3 of the drawings.

The leg portions 52 are turned outwardly adjacent the web portion of thestrip 56 to provide horizontal portions 60 that bear upon the L- shapedextensions 46. p

A plurality of longitudinal spaced, leaf springs 62 are anchored at oneof their ends to the Web portion of the channeled shaped element 24 andthe free ends of these springs 62 bear upon the web portion of thechannel strip 56 to resiliently urge the same downwardly upon theL-shaped extensions 45 so that the pivotal members 42 will be disposedin a substantially vertical plane with the strip 58 in a loweredposition.

The numeral 64 represents an actuating memher or bar that is providedwith a plurality of longitudinally spaced, transverse apertures 65 thatpivotally engage lugs 68 that are rigidly attached to or which form anintegral part of the legs of members 42.

Both terminals 79 and 12 of the bar 65 are externally threaded and oneterminal, for example, terminal Til receivably engages a pair of nuts14.

A coil spring 76 embraces the terminal 16, one end thereof engages thenuts 14, and its remaining end engages a lug 18 that projects inwardlyfrom the end plate 29 to urge the actuating rod in one direction and thepivotal members 42 in an inclined position relative to the supportmember 22 and strip 58 whereby the strip 58 will be raised to permit thedoor to be pivoted to a closed position.

Fixed to the inner face of end plate I8, is a pair of spaced ears 8!]that pivotally engage an arm 82 which is integrally formed with acontact or bearing member 84 having an outer end portion 86 thatslidably engages a guide opening 88 in the end plate I8.

An internally threaded socket 90 receivably engages the externallythreaded terminal 72 of the actuating bar 64 and is pivoted to thecontact member 84, by a suitable pin carried by the socket 99 that isreceived in a slot provided in the member 84.

In practical use of the present invention, the door l being in an openposition as shown in Figure l of the drawings, the end 86 of the contactmembers 84 extends outwardly from the guide opening 88, the pivotalmembers 42 are inclined and the strip 58 is raised. As the door [0 ismoved to a closed position, as shown best in Figure 2 of the drawings,the outer end 86 of the contact member 84 will engage the inclinedrecessed and bearing surface 92 of an anchor member 94 that is removablysecured to the frame [2, to force the outer end of the contact member 85inwardly, the actuating bar 66 toward the end plate 20, the pivotalmembers 42 to a substantially vertical position, and the strip 58 to alower position to engage the threshold 96.

Obviously, by omitting the lifting device, the present Weatherstrip canbe employed in conjunction with check-rail windows, overhead doors andthe like.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprebended by the spirit of theinvention as herein described and the scope of the appended claims.
